Abstract:
The invention relates, in general, to an improved process for preparing compounds (e.g., 3-(3-trifluoromethylphenyl)propanal (Compound III, below)), which are key intermediates for the synthesis of cinacalcet, its salts and/or solvates thereof, as well as the use of such compounds prepared by such process for the preparation of cinacalcet and/or its salts or solvates.
Abstract:
The invention relates, in general, to a new solid crystalline form of pantoprazole free acid (denominated "Form III"), salts derived therefrom (e.g., pantoprazole sodium and pantoprazole sodium sesquihydrate) and methods for producing the same. The invention further includes formulating pantoprazole free acid Form III, salts derived therefrom (e.g., pantoprazole sodium and pantoprazole sodium sesquihydrate) and/or in vivo cleavable prodrugs thereof (collectively "the compounds of the invention") into readily usable dosage units for the therapeutic treatment (including prophylactic treatment) of mammals, including humans.
Abstract:
This invention relates to the process of making geminal bisphosphonic acids and pharmaceutically acceptable salts and/or hydrates thereof which have the formula (I): wherein X 1 , X 2 , X 3 , X 1 R 1 and R 2 are described herein.
Abstract:
The invention relates to the preparation of losartan and its salts (e.g., losartan potassium). More particularly, the invention relates to the preparation of losartan and its salts (e.g., losartan potassium) in a simplified process that provides higher purity losartan potassium and losartan potassium having larger crystal sizes. The invention further includes formulating losartan, its salts (e.g., losartan potassium ) and/or in vivo cleavable prodrugs thereof (collectively "the compounds of the invention") into readily usable dosage units for the therapeutic treatment (including prophylactic treatment) of mammals, including humans.
